Mosėdis is one of the oldest towns in Samogitia, first mentioned in the writings of the Teutonic Knights in 1253. On the left bank of the Bartuva River stands the Mosėdis Hillfort, dating back to the 1st millennium. From 1421 to the 20th century, a manor belonging to the Bishop of Samogitia stood on the hillfort, and in 1544, the first church in this region of Samogitia was built. The current Church of St. Michael the Archangel in Mosėdžius was built in 1783. The church and the gates of the churchyard are architectural monuments. The publicist and priest K. Pakalniškis, who wrote under the pseudonym Dėdė Antanazas, worked here, as did the writer and priest J. Tumas-Vaižgantas, who founded the newspaper Tėvynės sargas in Mosėdis in 1896. There is a water mill near the Bartuva dam. In 1979, the Republican Vaclovas Intas Stone Museum was established there. It was created and nurtured by doctor Vaclovas Intas from 1957. The stone exhibition is displayed not only in the mill, but also in the Bartuva valley. It has a collection of more than 150,000 stones, ranging from the largest, weighing 50 tons, to stones weighing just a few grams. The original homestead of doctor Vaclovas Intas has also become a popular tourist attraction.
